Simply-
Does the frame manufacture have a website you can get help through? If not, we need to look at the wiring diagram, instructions that came with it to help you out. Can you scan it and post it as an attachment for us?
The LID type stuff is a little different to hook up than the standard tail light.

I am not sure if they do have a website or not, i did not check but it came with instruction whit wiring diagram, that which color is what should be. but i do not know the bike wiring diagram that, which one is ground, brake and negative and where do i have to conect them.

Tell us a little more. How did you connect it to your brake light? Do you have a meter?

If you just used those squeezon splicers then the only reason your brake light shouldn't work is that the device is very low impedence causing almost no current to flow thru the brake light. That doesn't make sense for a variety of reasons.

Have you checked your bulb? Check the connectors. Maybe you pulled a wire off the brake light during the install. Good luck,
Jerry

One problem that might crop up is that the brake light is monitored for failure. By adding this LED to the circuit you might wind up with a can of worms.

I am guessing you have a quad 'Back-off' license frame. If that is the case it will work fine with the EVO braking system without triggering a brake light fault. The LED assemblies do not draw enough current to upset the circuitry. My wife has one on her 2004 RS and I had one on my GT and earlier RS. The BMW color codes are:

brown = ground (brown is always ground on BMWs)
grey/yellow = brake light
grey/black = taillight

The 'Back-off' wiring instructions are here.

You would connect the black to the brown, the red to the grey/yellow and the white to the grey/black.

Hope this helps!

Hi Randy and thank you
Yes it is quad Back off from Signal Dynamics Corp. now my question is, can i connect the wiring to the break system directly? because when i did that before my break light stop working so where can i connect the wiring?
Thank you

Mine are wired directly to the wires to the taillight/brakelight socket. It worked fine on my 2004 K1200GT and is working fine on my wife's 2004 K1200RS and 2005 R1200RT as well as my 2005 LT. All of these bikes use the same bulb current monitoring circuitry.

Hi
I will try one more time and i hope it works. so if it take the taillight/breaklight and conect the wiring it should work.
I let you know Randy
Thank you again
